Embodiment Construction

[0061] figure 2 The steps of the embodiment of the method according to the invention shown in are detailed as follows:

[0062] - Modeling by the dentist via an intraoral scanner

[0063] - Generate digitized model data

[0064] - Optional: forward the digitized model to the laboratory

[0065] - Digital tooth creation

[0066] - Optional: Digitize the 3D data set into red (gingiva), white (teeth (dental arch)) and / or gray earlier model castings in the case of body-supported partial dentures)

[0067] - Manufacture of individual elements, utilizing connecting elements if necessary

[0068] - where the inside of the tooth or tooth arch is produced by an automated method and at least one second material is applied thereon as an outer layer by an automated method (preferably the inside of the tooth is produced by means of milling or SLA or inkjet printing (inner core) and at least one second material is applied to the interior with FDM)

[0069] - Connecting the individua...

Abstract

In the method for manufacturing full or partial dentures: A) providing 3D data of the oral cavity situation in the state without teeth or with partial teeth; B) digitally constructing the denture base for the lower and upper jaw respectively; C) digitizing accurately create virtual teeth with a matching occlusion and tooth shapes chosen according to esthetic criteria; in the case of complete dentures: D1) using an automated method from the group consisting of methods for building layers and methods for grinding materials and D2) using an automated method from the group consisting of a method of building layers and a method of grinding material to make a denture base; or in the case of a partial denture: D1) using a method consisting of a building layer and D2) using an automated method of the group consisting of a method of building layers and a method of grinding material to manufacture the support structural or fixed elements.

Description

technical field [0001] The present invention relates to a method for the automated manufacture of dentures, in particular the manufacture of individual dentures from digitally extracted data of oral conditions via CAD / CAM and rapid manufacturing / rapid prototyping. Background technique [0002] The manufacture of complete dentures and partial dentures is carried out according to known methods. Mention is to be made, for example, of the conventional methods of powder / fluid technology, as known for a long time and described in the literature (eg EP 1 243 230 A2, US 6 881360 B2 and "Ullmann's Encyclopedia of Industrial Chemistry Copyright 2002 by Wiley-VCH Verlag "Dental Materials" in "). [0003] Three different main material classes are generally known for the manufacture of full denture articles. They are two-component materials based on polymethylmethacrylate (PMMA) [commercial products Palapress, Paladur (Heraeus Kulzer, DE), SR 3 / 60® Quick (Ivoclar, LI), Degupress ® (Deg...
